Problems with Program Monitor Size?

Hi all,

I've been editing a sequence and things were going dandy until the Program monitor size changed for the smaller.

Here's a screen shot if you would like to take a look:

Here, the same video is playing, but in the source monitor the width of the monitor is longer while the program monitor's screen's width is less and also magnified.

Can anyone help me get both screens the same magnification and width?

They both have the same magnification (both on fit) and have the same resolution if that helps...

Thanks,
